` IMPROVEMENT IN WATER-WHEELS.

`The Schedule referred to in these Letters Patent andmaking part ot tnosame.

To all whom 'it may concern:

Be itknown that I, WILLIAM E. HLLL, of Renovo, in the county of Clinton,and State -of Pennsylvania,L have invented a new and useful Improvementin Water-Wheels; and I do hereby declare that the following is a full,clear, and exact description thereof,

panying drawings, forming part of this specification. This inventionrelatesto improvements in tin-bine water-wheels, whereby it is designedt0 improve the eicacy ot' the same.

The invention consists in an improved arrangement horizontal section of''my im- I make the buckets in two parts, 'c and b, the parts a beingfixed near the outer edges -oi' the rims gentially, orthereabout,toeth'e curvature ot the inner circle ot the rims. l l

`The innerends of the parts bare free to swing ou the pivots c. The saidparts b are curved, presenting a convex surface to the water as itpasses beyond th'e parts a.

Behind these parts b, springsd, secured to studs e,

are arranged, to bear upon the free ends in afmanner to cause the partsb top close the'issues.

The object of thisjarrangement is to adapt the capacity of the issues tothe volume of water passing throughthe wheel, or to the resistance uponthe wheel, to close; them when the volume is small, so as to obtain thereactive force thereof, or to open when the volume isl large; or if theresistance upon the wheel increases so as to reduce itsspced, thebuckets will open under the increased pressure ot' the water, to al-410W agreater amount to pass through, and thereby exert a greater powerto overcome the resistance.

As a further means of regulating the flow of water,

I provide, in addition to the outer gate Vj, the curvedl inner gate g,whereby the volume of water vmay be better adjusted to the capacity ofthe buckets to pass I propose to pack the joints between the wheel andthe scroll by meansl ot' grooves in the one. lined with India-rubberpacking, and corresponding V-projections on the other, as represented ath, and as a simple means of forming the said grooves, I provide therings i, upon the upper-and lower parts oi' the scroll, and form thesaid grooves, halfin each.

Having thus described my invention,

I claim as'new, and desire to secure by vLettersV l. The buckets,composed of the fixed and Inovable parts, and the 'latter provided withsprings, all substantially as specified. y i

2. lThe gates fg, arranged and combined with the wheel,having bucketsarranged substantially as herein specified. Y A y 3. In combination withthe wheel and scroll, the V-grooves lined with India rubber, andarranged with the V-projections of the `wheel, as specified.
